Abstract
A head suspension assembly including a stainless steel hinge member, an integrated lead flexure and a polymer stiffener member. The stainless steel hinge member includes a proximal mounting region, a beam region having a load point dimple, and a spring region between the mounting and beam regions. The integrated lead flexure is attached to the hinge member and has a slider bond pad engaged by the load point dimple. The stiffener member is molded onto the beam portion of the hinge member and attached by rivets extending through apertures in the hinge member.
Claims26
A head suspension assembly, including:
- a spring material hinge member including a proximal mounting region, a beam region having a first load element, and a spring region between the mounting region and beam region;
- a polymer stiffener member attached to the beam region of the hinge member;
- and
- an integrated lead flexure including a slider bond pad having a second load element attached to the beam region of the hinge member, the second load element in cooperative engagement with the first load element to provide a load point for the slider bond pad.
A head suspension assembly, including:
- a spring metal hinge member having one or more apertures and including a proximal mounting region, a beam region, a spring region between the mounting region and beam region, and a flexure region having a load point;
- electrical traces extending from the flexure region over at least portions of the hinge member;
- insulating material between the traces and adjacent portions of the hinge member;
- and;
- a polymer stiffener member attached to the beam region of the hinge members including rivets extending through the apertures in the hinge member to attach the stiffener member to the hinge member.
A head suspension assembly, including:
- a spring metal hinge member including a proximal mounting region, a beam region, a spring region between the mounting region and beam region, and a flexure region having a load point;
- electrical traces extending from the flexure region over at least portions of the hinge member;
- insulating material between the traces and adjacent portions of the hinge member;
- and;
- a polymer stiffener member including a head lift attached to the beam region of the hinge member.
A head suspension assembly, including:
- a spring metal hinge member including a proximal mounting region, a beam region, a spring region between the mounting region and beam region, and a flexure region having a load point;
- electrical traces extending from the flexure region over at least portions of the hinge member;
- insulating material between the traces and adjacent portions of the hinge member;
- and;
- a polymer stiffener member attached to the beam region of the hinge member, the stiffener member including a gimbal portion extending over at least a portion of the flexure region of the hinge member.
